摘要
就资源再生利用而言,粉煤灰作为地基回填材料已被广泛应用于工程中。结合郑州电厂粉煤灰沉淀场地对粉煤灰的工程性质进行了系统的研究,同时对现场试桩进行了粉煤灰土层的桩側摩阻力测试和单桩水平静载试验,对地基土水平抗力系数的比例系数值和单桩水平承载力特征值的取值进行了分析,为工程结构设计提供了可靠依据。
Considering regeneration and utilization of resources, coal ash is extensively used as foundation backfill material in projects. This paper systematically researches engineering property of coal ash according to conditions of coal ash deposit ground of Zhengzhou Power Plant, and tests of side skin friction in coal ash layer and single pile horizontal static load are carried out on test piles, providing reliable basis for engineering structural design.
